I think I know the answer to this but before I do it I just wanted to make sure there's nothing I'm missing. I'm cleaning out my oil cabinet & have some Mobil 1 5w30, Mobil 1 10w30, & Amsoil 5w30 synthetic. Would I have any problem using all of these on my next oil change?

Replying to: ruking1 (Nov 13, 2007 8:26 am) So these 2 oils are pretty much seen as equals? Nobody thinks one is even a little better than the other? lol And anyone had any luck finding Mobil 1 0W30?

Replying to: smokey75 (Nov 13, 2007 9:10 am) The real keys are there statistical correlations!!?? Practically speaking, are the premiums worth the performance? So for example, if  PAR, I would convert all 5w30 applications to 0w30 in a heartbeat. Given premium, does the (so called ) performance advantage pencil out?

Replying to: ruking1 (Nov 13, 2007 9:18 am) 45,000 miles ago, I decided to go from the oem filled 5w20 conventional oil to 0w20 Mobil One. So I bought a supply of 1 qt bottles at discount. I have been getting between 38-42 mpg. Now I did notice (beginning with the first tankful) an IMMEDIATE jump in the RANGE of mpg (1-3 mpg) Now because of the decision to switch, I have not done an A/B test (but have noticed a distinct difference) let alone an A/B and BACK to A test. I just recently bought some 5 qt containers of 5w20 Mobil One 23 bux and change. My perception is no premium or par to the 0w20. So it will be a no brainer to do the next oil change interval (20,000 miles) to see if there is a performance difference due to the viscosity difference of 0w20 vs 5w20. I swag little to no difference.But if there will be, I would anticipate 1-2 mpg difference. So it is up to YOU (me, in my case) to decide whether the viscosity is worth either the premium or the discount.

Instead of which hydro cracked product is REALLY synthetic or NOT!? Interesting article ..."LongLife Service regimes The LongLife Service regime is so called because there are no set service intervals and, depending on how you drive your vehicle, and the conditions of use, a service will be required anywhere between 9,000 miles or 12 months (whichever occurs first), up to a maximum of 20,000* miles or 24 months (whichever occurs first)."... http://www.vw.co.uk/assets/Longlife_servicing.pdf |
